Meanwhile, the moving mechanism 3 further includes a rotating member. The rotating member may be a rotating shaft which is located at the center of the base plate, and a rotating shaft is respectively fitted to one end of the first rotating arm 31 and the second rotating arm 32 at both sides, and the other end is connected to the connecting arm. The number of the rotation shafts may be selected as needed, and in the present embodiment, the rotation shafts are preferably two, including the first rotation shaft 33 and the second rotation shaft 34. Specifically, the bottom plate 7 includes a first layer bottom plate and a second layer bottom plate, the first layer bottom plate is located above the second layer bottom plate, the guide mechanism 5 is disposed on the first layer bottom plate, and the rotating member is disposed on the second layer bottom plate. That is, the first rotation shaft 33 and the second rotation shaft 34 are symmetrically disposed on the second floor panel, and the first rotation shaft 33 is connected to the first pivot arm 31 and the second rotation shaft 34 is connected to the second pivot arm 32. Through setting up this rotating member for the rocking arm rotates round the rotating member under actuating mechanism 4's effect, thereby can be more stable drive the linking arm and rotate, realize the stable and limited switching of first kuppe 11 and second kuppe 12.
The driving mechanism 4 is used for driving the first rotating arm 31 and the second rotating arm 32 to perform relative movement, so as to drive the first pod 11 and the second pod 12 to perform opening and closing operations. The drive mechanism 4 includes a first drive member 41 and a second drive member 42. The first driving member 41 is in driving connection with the first rotating arm 31, and the second driving member 42 is in driving connection with the second rotating arm 32.

Preferably, the driving mechanism 4 may be a pneumatic cylinder, a hydraulic cylinder, or the like.
The locking mechanism 6 is arranged between the driving mechanism 4 and the movement mechanism 3, and avoids the anti-creeper energy absorption device from the driving mechanism 4, so that the self-locking function can be realized; meanwhile, the arrangement of the locking mechanism 6 solves the problem that the gap of the air guide sleeve mechanism 1 is not tight due to the mechanism gap of the existing shutter. Specifically, the locking mechanism 6 includes a cylinder body, a roller device and a spring are arranged in the cylinder body, one end of the cylinder body is pre-pressed with the roller device, the roller device is in rolling connection with the corresponding rotating arm through the roller device, the rolling device can roll in the corresponding rotating arm, and meanwhile, the other end of the cylinder body is connected with the driving mechanism 4, so that the locking mechanism 6 can be pushed to move under the action of the driving mechanism 4. More specifically, the locking mechanism 6 is provided on the second floor panel. The locking mechanism 6 comprises a first locking piece 61 and a second locking piece 62, one end of the first locking piece 61 is connected with the power output end of the first driving piece 41, and the other end of the first locking piece is connected with the first rotating arm 31; the second locking member 62 has one end connected to the power take-off of the second driver 42 and the other end connected to the second pivot arm 32. Therefore, the locking mechanism 6 can rotate around the bottom plate 7 under the action of the driving mechanism 4, and further can drive the first rotating arm 31 and the second rotating arm 32 to rotate, and drive the first connecting arm 21 and the second connecting arm 22 to move under the action of the two rotating arms; meanwhile, the other end of the first connecting arm 21 is connected to the first slider 53, and the other end of the second connecting arm 22 is connected to the second slider 54. The other end of the first connecting arm 21 will therefore follow the slider along the corresponding guide rail, so that the action of the first connecting arm 21 and the second connecting arm 22 is no longer a pure rotational action about the axis of rotation. Because the air guide sleeve mechanism 1 is arranged on the connecting mechanism 2, the air guide sleeve mechanism 1 also moves along with the movement of the connecting mechanism 2, thereby realizing the opening and closing actions of the air guide sleeve mechanism 1. Further, when the lock mechanism 6 moves, a mechanism dead point is formed between the first pivot arm 31 and the second pivot arm 32, and when the lock mechanism 6 partially goes over the mechanism dead point at the time of locking, a mechanical self-locking angle is generated, and a self-locking function is exerted, so that the opening/closing mechanism is locked and held at a predetermined position.
Meanwhile, in order to facilitate manual unlocking, the lower end of the locking mechanism 6 is provided with an unlocking interface 8 for manual unlocking and manual locking, and manual unlocking or manual locking are operated through the unlocking interface 8. When manual unlocking is needed, the first rotating arm 31 and the second rotating arm 32 can be driven to rotate around the rotating shaft only by rotating the locking mechanism 6 through an inner hexagonal wrench, and reversely cross a mechanism dead point, so that unlocking or locking of the opening and closing mechanism is completed. Through the structure, manual unlocking or manual locking is simple and easy to operate.
Further, as shown in fig. 6 and 7, a limit stopper is further disposed on the bottom plate, the limit stopper includes an opening limit stopper 9 and a closing limit stopper 10, and the opening limit stopper 9 and the closing limit stopper 10 respectively limit movement of the rotating member when the pod mechanism 5 is in the fully opened state and the fully closed state.
In order to more clearly illustrate the present application, the working principle of the present invention is further illustrated by the embodiments shown in fig. 1 to fig. 7 as follows:
when the air guide sleeve mechanism 1 is opened, the driving mechanism 4 pulls back the locking mechanism 6 to rotate, at this time, the locking mechanism 6 drives the first rotating arm 31 and the second rotating arm 32 to rotate around the rotating shaft, at the same time, under the driving of the two rotating arms, the first connecting arm 21 and the second connecting arm 22 respectively drive the first sliding part 53 and the second sliding part 54 to slide along the guide rail, when the air guide sleeve mechanism 1 is driven by the first connecting arm 21 and the second connecting arm 22 to move to the opening state, at this time, the locking mechanism 6 continues to rotate, when the locking mechanism 6 rotates to be perpendicular to the corresponding rotating arm (namely, a mechanical "dead point" critical point), at this time, the pressure spring of the locking mechanism 6 is compressed to the shortest, the locking mechanism 6 continues to rotate in the corresponding rotating arm, the pressure spring is released, at this time, the angle between the locking mechanism 6 and the corresponding rotating arm is smaller than 90 degrees, a mechanical self-locking angle is generated, a self-locking function is achieved, and the opening and closing mechanism is locked, so that the air guide sleeve mechanism is kept at the opening position.
When the front-end dome mechanism 1 is closed, the driving mechanism 4 pushes the locking mechanism 6 to rotate, and simultaneously drives the first rotating arm 31 and the second rotating arm 32 to rotate around the rotating shaft, and simultaneously, under the driving of the two rotating arms, the first connecting arm 21 and the second connecting arm 22 respectively drive the first sliding part 53 and the second sliding part 54 to slide along the guide rail, and when the dome mechanism 1 moves to a closed state under the driving of the first connecting arm 21 and the second connecting arm 22, the locking mechanism 6 continues to rotate and is compressed against the pressure spring force. When the locking mechanism 6 rotates to be perpendicular to the corresponding rotating arm (namely, a mechanical 'dead point' critical point), the pressure spring of the locking mechanism 6 is compressed to be the shortest, the locking mechanism 6 is continuously rotated, the pressure spring is released, at the moment, the angle between the locking mechanism 6 and the corresponding rotating arm is smaller than 90 degrees, a mechanical self-locking angle is generated, a self-locking function is exerted, and the opening and closing mechanism is locked, so that the opening and closing mechanism is kept at a closed position.
In summary, by adopting the above mechanism, the pod mechanism 1 realizes the controllability of the movement locus thereof under the mutual cooperation of the connecting mechanism 2, the moving mechanism 3, the driving mechanism 4 and the guiding mechanism 5. Since the guide mechanism 5 can be changed according to actual needs, and the motion trail of the dome mechanism 1 is determined by the guide mechanism 5, the motion trail of the opening and closing mechanism can be changed along with the change of the guide mechanism 5. Therefore, the movement track of the air guide sleeve mechanism 1 can be accurately controlled by changing the shape and the position of the guide mechanism 5, so that the condition of interference with the internal parts of the vehicle body can be effectively solved. Therefore, the technical problem that the motion track of the front end opening and closing mechanism cannot be changed in the prior art is solved.
